Recording material

Abstract

A recording material comprising an electron donating colorless dye and an electron accepting compound is disclosed, the recording material further comprising, as a heat-fusible substance, a benzyl ether derivative represented by formula (I): ##STR1## wherein R represents a halogen atom or a substituted or unsubstituted alkoxy group; and when R is a substituted or unsubstituted alkoxy group, X, Y and Z, which may be same or different, each represents a hydrogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkoxy group or a halogen atom; and when R is a halogen atom, X represents a substituted or unsubstituted alkoxy group, and Y and Z each represents a hydrogen atom. The recording material exhibits improved color developability and color forming sensitivity.

What is claimed is: 
     
       1. A recording material comprising a support having provided thereon an electron donating colorless dye, an electron accepting compound, and a benzyl ether derivative represented by formula (I): ##STR4## wherein R represents a halogen atom or a substituted or unsubstituted alkoxy group; and when R is a substituted or unsubstituted alkoxy group, X, Y and Z, which may be the same or different, each represents a hydrogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkoxy group or a halogen atom; and when R is a halogen atom, X represents a substituted or unsubstituted alkoxy group, and Y and Z each represents a hydrogen atom. 
     
     
       2. The recording material as claimed in claim 1, wherein at least one of R, X, Y, and Z is an alkoxy group, and at least one of the other group is a halogen atom. 
     
     
       3. The recording material as claimed in claim 1, wherein the alkoxy group contains from 1 to 4 carbon atoms. 
     
     
       4. The recording material as claimed in claim 1, wherein the benzyl ether derivative is represented by the formula (II): ##STR5## wherein X 1  represents an alkoxy group, and R 1  represents a halogen atom. 
     
     
       5. The recording material as claimed in claim 1, wherein the benzyl ether derivative is represented by the formula (III): ##STR6## wherein X 2  represents an alkyl group or an alkoxy group, and R 2  represents an alkoxy group. 
     
     
       6. The recording material as claimed in claim 1, wherein the benzyl ether derivative is represented by the formula (IV): ##STR7## wherein X 3  represents a halogen atom, Y 1  and Z 1  represents a hydrogen atom or an alkyl group, and R 2  represents an alkoxy group. 
     
     
       7. The recording material as claimed in claim 1, wherein said benzyl ether derivative is present in an amount of from 50 to 200% by weight based on the electron accepting compound. 
     
     
       8. The recording material as claimed in claim 1, wherein said benzyl ether derivative is 4-ethoxyphenyl-4'-chlorobenzyl ether. 
     
     
       9. The recording material as claimed in claim 1, wherein said benzyl ether derivative is 3-methyl-4-chlorophenyl-4'-methoxybenzyl ether. 
     
     
       10. The recording material as claimed in claim 1, wherein said benzyl ether derivative is 4-chlorophenyl-4'-methoxybenzyl ether. 
     
     
       11. The recording material as claimed in claim 1, wherein said benzyl ether derivative is 4-methylphenyl-4'-methoxybenzyl ether. 
     
     
       12. The recording material as claimed in claim 1, wherein said benzyl ether derivative is 3,5-dimethyl-4-chlorophenyl-4'-methoxybenzyl ether. 
     
     
       13. The recording material as claimed in claim 1, wherein said benzyl ether derivative is 4-fluorophenyl-4'-ethoxybenzyl ether. 
     
     
       14. The recording material as claimed in claim 1, wherein said benzyl ether derivative is 4-methoxyphenyl-4'-chlorobenzyl ether.
